The third lane changing device 6 can guide the empty material cup 200 on the third conveying line 3 and the empty material cup 200 on the second conveying line 2 onto the first conveying line 1, and as the first conveying line 1 is annular, the empty material cups 200 can flow back to the battery cell wire feeding station 7 and perform the battery cell wire feeding process again.

According to the annular conveying line for producing the electric core, the electric core is placed in the material cup 200 at the electric core wire-feeding working position 7, the material cup 200 which passes through the electric core wire-feeding process is sent out by the first conveying line 1, the material cup 200 which supports the electric core on the first conveying line 1 is guided to the second conveying line 2 by arranging the first channel changing device 4, and the empty material cup 200 on the first conveying line 1 is guided to the third conveying line 3, so that the split-flow conveying of the empty material cup 200 and the unoccupied material cup 200 is realized; the second lane changing device 5 can guide the material cup 200 bearing the battery cell to the first conveying line 1, or enable the material cup 200 bearing the battery cell to still be conveyed along the second conveying line 2, so that the first conveying line 1 and the second conveying line 2 can both convey the material cup 200 bearing the battery cell to the battery cell offline station 8, and the annular conveying line can accommodate more material cups 200 bearing the battery cell, and accumulation of the material cups 200 is avoided; meanwhile, the empty material cup 200 on the third conveying line 3 and the empty material cup 200 passing through the offline process on the second conveying line 2 are guided to the first conveying line 1 by the third lane changing device 6 and finally flow back to the battery cell online station 7, so that the material cup 200 can be reused, and the problem that the battery cells which are arranged vertically are difficult to transfer efficiently by the conventional battery cell conveying line is solved.

In some embodiments, the second conveyor line 2 is arranged outside the first conveyor line 1, so that more cups 200 can be accommodated on the second conveyor line 2. The number of empty material cups 200 is relatively small because the unqualified battery cells are detected after the operation process of the first battery cell station, so that the length requirement on the third conveying line 3 is not high, and the third conveying line 3 is arranged on the inner side of the first conveying line 1; the first end of the second conveyor line 2 and the first end of the third conveyor line 3 are arranged side by side on opposite sides of the first conveyor line 1; the second end of the second conveyor line 2 and the second end of the third conveyor line 3 are arranged side by side on opposite sides of the first conveyor line 1; the first lane changing device 4 is arranged between the first end of the second conveying line 2 and the first end of the third conveying line 3; the third lane-changing device 6 is arranged between the second end of the second conveyor line 2 and the second end of the third conveyor line 3.

Specifically, when the empty material cup 200 is conveyed to the battery cell wire-feeding station 7 by the first conveying line 1, under the condition that the screw 93 rotates, the material cup 200 can enter from one end of the groove, so that the material cup 200 is sequentially limited in the groove on the screw 93, and as the material cups 200 positioned at the battery cell wire-feeding station 7 are all positioned on the same side of the screw 93, the intervals between any two adjacent material cups 200 in the plurality of material cups 200 limited in the groove are equal, the battery cell is conveniently placed in the material cup 200, and the process of waiting for the battery cell wire-feeding is completed.

Along with the rotation of the screw 93, the screw 93 can drive the plurality of material cups 200 limited in the groove to synchronously move through the groove until the material cups 200 are moved out of the other ends of the groove and separated from the screw 93, and the separated material cups 200 (after the process of feeding the battery cells) are sent out by the first conveying line 1. It should be noted that the rotation driving mechanism 92 may include a motor and a belt-pulley transmission mechanism.

In a specific embodiment, the battery cell on-line station 7 is provided with an incoming material sensor, the incoming material sensor comprises a plurality of material cup incoming material sensors and a plurality of battery cell incoming material sensors, the plurality of material cup incoming material sensors are uniformly arranged at intervals along the axis direction of the screw 93, the sensing height of the material cup incoming material sensors is lower than the height of the material cup 200, so that whether the material cup 200 reaches a preset area is sensed, and when all the material cup incoming material sensors sense that the material cup 200 reaches the preset area, the battery cell is placed in the material cup 200; the plurality of electric core incoming material sensors are uniformly arranged at intervals along the axis direction of the screw 93, the electric core incoming material sensors are lower than the electric core in height, so that whether the electric core is placed in the material cup 200 is sensed, when all the electric core incoming material sensors sense that the electric core is supported by the material cup 200, the screw 93 further rotates, the material cup 200 is gradually separated from the screw 93, and the separated material cup 200 (together with the electric core inside the material cup) is sent out by the first conveying line 1.

As shown in fig. 2-3, in some embodiments, the first lane changing device 4 includes a first lane changing guide 41, a second lane changing guide 42, and a third lane changing guide 43; the first lane changing guide 41 and the second lane changing guide 42 are arranged on the upper side of the first conveyor line 1 at intervals, and the first lane changing guide 41 is arranged on the rear side of the second lane changing guide 42 along the conveying direction of the first conveyor line 1; the third lane changing guide 43 is arranged on the upper side of the second conveyor line 2, the third lane changing guide 43 and the first lane changing guide 41 are oppositely arranged, and a first reversing channel is formed between the third lane changing guide 43 and the first lane changing guide 41; the first reversing channel is used for guiding the material cup 200 bearing the battery cell to move from the first conveying line 1 to the second conveying line 2; the height of the first channel changing guide 41 is larger than the height of the material cup 200 and smaller than the height of the battery cell (the height of the upper end of the battery cell when the battery cell is positioned in the material cup 200); the second lane change guide 42 is used to guide the empty gob 200 on the first conveyor line 1 to move to the third conveyor line 3.

Specifically, since the height of the first channel changing guide 41 is smaller than the height of the battery cell, the battery cell can be conveyed by the first conveying line 1 to be propped against the first channel changing guide 41, the battery cell and the material cup 200 containing the battery cell are guided by the first channel changing guide 41 to the second conveying line 2, a first reversing channel is formed between the third channel changing guide 43 and the first channel changing guide 41, and when the battery cell is in the first reversing channel, the third channel changing guide 43 and the first channel changing guide 41 limit the battery cell together to guide the battery cell and the material cup 200 to be conveyed forwards, so that the battery cell and the material cup 200 are prevented from toppling.

Since the height-limiting height of the first lane-changing guide 41 is greater than the height of the cup 200, the empty cup 200 can pass under the first lane-changing guide 41, the height-limiting height of the second lane-changing guide 42 is less than the height of the cup 200, and the cup 200 can move against the second lane-changing guide 42 and be guided to the third conveyor line 3 by the second lane-changing guide 42.

Specifically, when the fifth lane change guide 52 is in the first position, the height of the fifth lane change guide 52 is smaller than the height of the battery cell, and the material cup 200 or the battery cell on the second conveying line 2 is guided to move from the second lane change guide to the first conveying line 1 when contacting the fifth lane change guide 52, the second lane change guide 51 and the fifth lane change guide 52 form a second lane change channel capable of limiting the material cup 200 or the battery cell in the second lane change channel.

When the fifth lane-changing guide 52 is in the second position, the fifth lane-changing guide 52 is away from the second conveyor line 2 and the cups 200 (or cells) on the second conveyor line 2 do not contact the fifth lane-changing guide 52, and the cups 200 on the second conveyor line 2 are still continuously conveyed by the second conveyor line 2.

In a specific embodiment, the sensing assembly includes a first buffer sensor and a second buffer sensor (not shown in the figure), where the first buffer sensor, the second buffer sensor and the buffer assembly are sequentially disposed along the conveying direction of the second conveying line 2, and the second buffer sensor is adjacent to the buffer assembly. When the buffer assembly blocks the passing of the material cups 200, the buffer process of the material cups 200 is started until the first buffer sensor senses the existence of the material cups 200 in the sensing area and the material cups 200 are not moved, the buffer assembly allows the material cups 200 to pass until the second buffer sensor senses the material cups 200 in the sensing area, the buffer assembly blocks the material cups 200 to pass, and the buffer process is repeated.
